An electrician for the Capital Hilton Hotel, a bus driver for Tourmobile and a special services agent for Eastern Airlines will be honored tomorrow by the Washington Convention and Visitors Association for their contributions to the local tourism industry.

Harold Beall, who is in charge of the technical machinery that powers the Capital Hilton, will receive the association's gold award, which is accompanied by a $1,000 prize. He will be cited for his work over the past 15 years on events such as the inaugural balls of presidents Nixon, Carter and Reagan.

David E. Daniels, a driver and guide for Tourmobile for nine years, will receive the association's silver award, which comes with $500. Daniels was cited by his employer for his hospitality, sense of humor, patience and compassion.

Holly L. Olson of Eastern Airlines will also receive the silver award. Olson has been an Eastern special services agent for two years, solving such passenger problems as lost luggage and taking extraordinary measures such as driving an unaccompanied child home from the airport in a blizzard.

The association will also cite 48 other individuals who work in Washington's tourist industry during the award ceremony, scheduled for 11:45 a.m. at the Capital Hilton.
